I'm in the process of clearing driveways that have well over a foot of very hard packed snow on them. To my suprise I'm having to work the machine very hard to make any progress and I'm looking for suggestions on how to maybe make this easier. I have a simple straight blade on my Case 90xt. It's -30 outside and like I said this snow is very hard packed. My current technique is to drop the blade straight down like a knife and then crawl forward every 4-6 inches until I get about 4 feet of broken snow then back up and scoop. The inching forward and chopping just seems to take forever and the chopping motion of the blade seems very hard on the machine and concret under the snow. If I square off a section and then take a run at it my blade just bounces up on top of the snow no matter what angle I try and set the bucket at. Of course my front wheels are off the ground to get max weight onto the bucket to keep it from hopping up on top of the snow. If I try pushing forward more slowly the hard packed snow just stops me in my tracks and I spin my tires. Would teeth on the bucket be more ideal for this kind of work? Any other suggestions are appreciated.
